Park workers seeking damages beaten, says lawyer Scuffles broke out in front of China Eastern Airlines' Shanghai headquarters on Monday as more than 40 employees of Nanhai Park in Baotou, Inner Mongolia, sought compensation for a plane crash that destroyed the park's business. Holding a banner that read 'I want to feed myself', the protesters staged a sit-in as they waited for airline officials to respond to their calls for millions of yuan in damages. About 80 police officers and security guards were deployed to try to seize the banner and drive the protesters away, their lawyer Zhang Qihuai told the South China Morning Post. Two female workers, Zhang Lingzhi and Han Jun, were beaten and later treated for head and wrist injuries in hospital, said the lawyer representing the pair. Mr Zhang said he sent a letter to the carrier yesterday morning asking for an explanation and compensation for the 'brutality which resulted in the workers' injuries'. China Eastern Flight MU5210 to Shanghai burst into flames less than a minute after takeoff from Baotou on November 21 last year and plunged into a lake in the park, claiming the lives of all 47 passengers and six crew on board, along with two people on the ground. Park managers filed a lawsuit this month over the cleanup costs and economic fallout from the crash, totalling more than 100 million yuan. Since the accident the park has halted its operations, which included tourism, fishing and catering businesses. 'We have not received our salary since the accident took place,' said Li Ying , one of the workers who travelled to Shanghai. He said they had received only 500 yuan a month from the Baotou government in emergency relief after the crash, while their normal salary had been about 1,500 yuan. 'The China Eastern representatives promised to pay us in September and October, but they never did,' Mr Li said. Zhang Tao , a 44-year-old petitioner, said she spent the night outside the airline's office building on Monday. 'We borrowed money to go to Shanghai,' she said. 'When we asked for accommodation, nobody listened to us.' She said she would sleep in the same place in the coming days and would not leave without a promise from the airline. China Eastern Airlines was not available for comment.
